CARTRIDGE VALVES
The MVP
®
snowplow FloStat
®
hydraulic system performs 10 blade
movement functions.
All functions require the vehicle
ignition (key) switch to be in the run
or accessory position and the power
to be activated on the snowplow cab
control.
Nine of the ten hydraulic functions
require energizing the electric motor,
shifting of solenoid cartridge spools
or activating P/O check valves. The
tenth function,
lower
, does not
energize the motor but requires
shifting of solenoid cartridges.
